Limitations of the system

Smart Cruise Control system may have limits to its ability to detect distance to the vehicle ahead due to road and traffic conditions.

Driving on a curve

  • Smart Cruise Control system may not detect a moving vehicle in your lane, and then your vehicle could accelerate to the set speed. Also, the vehicle speed will decrease when the vehicle ahead is recognized suddenly.

  • Select the appropriate set speed on curves and apply the brakes or accelerator pedal if necessary.

Your vehicle speed can be reduced due to a vehicle in the adjacent lane.

Apply the accelerator pedal and select the appropriate set speed. Check to be sure that the road conditions permit safe operation of Smart Cruise Control.

Driving on a slope

  • During uphill or downhill driving, Smart Cruise Control system may not detect a moving vehicle in your lane, and cause your vehicle to accelerate to the set speed. Also, the vehicle speed will rapidly decrease when the vehicle ahead is recognized suddenly.

  • Select the appropriate set speed on inclines and apply the brake or accelerator pedal if necessary.

Changing lanes

  • A vehicle which moves into your lane from an adjacent lane cannot be recognized by the sensor until it is in the sensor's detection range.

  • The radar may not detect immediately when a vehicle cuts in suddenly. Always pay attention to the traffic, road and driving conditions.

  • If a slower vehicle moves into your lane, your speed may decrease to maintain the distance to the vehicle ahead.

  • If a faster vehicle which moves into your lane, your vehicle will accelerate to the set speed.

Recognizing the vehicle

Some vehicles in your lane cannot be recognized by the sensor:

  • Narrow vehicles such as motorcycles or bicycles

  • Vehicles offset to one side

  • Slow-moving vehicles or sudden- decelerating vehicles

  • Stopped vehicles

  • Vehicles with small rear profile such as trailers with no loads

A vehicle ahead cannot be recognized correctly by the sensor if any of following occurs:

  • When the vehicle is pointing upwards due to overloading in the luggage compartment

  • While the steering wheel is operating

  • When driving to one side of the lane

  • When driving on narrow lanes or on curves

Apply the brake or accelerator pedal if necessary.

  • Your vehicle may accelerate when a vehicle ahead of you disappears.

  • When you are warned that the vehicle ahead of you is not detected, drive with caution.

  • When driving in stop-and-go traffic, and a stopped vehicle in front of you merges out of the lane, the system may not immediately detect the new vehicle that is now in front of you. In this case, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

  • Always look out for pedestrians when your vehicle is maintaining a distance with the vehicle ahead.

  • Always be cautious for vehicles with higher height or vehicles carrying loads that sticks out from the back of the vehicle.

Warning

When using Smart Cruise Control take the following precautions:

  • If an emergency stop is necessary, you must apply the brakes. Smart Cruise Control system may not be able to completely stop the vehicle or avoid a collision in every situation.

  • Keep a safe distance according to road conditions and vehicle speed. If the vehicle to vehicle distance is too close during a high-speed driving, a serious collision may result.

  • Always maintain sufficient braking distance and decelerate your vehicle by applying the brakes if necessary.

  • Smart Cruise Control system cannot recognize a stopped vehicle, pedestrians or an oncoming vehicle.

    Always look ahead cautiously to prevent unexpected and sudden situations from occurring.

  • Vehicles moving in front of you with a frequent lane change may cause a delay in the system's reaction or may cause the system to react to a vehicle actually in an adjacent lane.

    Always drive cautiously to prevent unexpected and sudden situations from occurring.

  • Always be aware of the selected speed and vehicle to vehicle distance. The driver should not solely rely on the system but always pay attention to driving conditions and control your vehicle speed.

  • Smart Cruise Control system may not recognize complex driving situations so always pay attention to driving conditions and control your vehicle speed.

  • For safe operation, carefully read and follow the instructions in this manual before use.

  • Do not use Smart Cruise Control system on steep inclines or when towing another vehicle or trailer since such extreme loading can interfere with your vehicle's ability to maintain the selected speed.

  • Do not use Smart Cruise Control when the vehicle is towed.

Notice

Smart Cruise Control system may not operate temporarily due to:

  • Electrical interference

  • Modifying the suspension

  • Differences of tire abrasion or tire pressure

  • Installing different type of tires
